Answer:
All real numbers
Step-by-step explanation:
There is 3 possible solutions to a linear equation:
- One solution -a unique x value that makes the equation true
- No solution - a false statement is given after solving without a value for x
- Infinite solution - a true statement is given after solving without a value for x
Solve using inverse operations:
4(a+2)=14-2(3-2a)
4a+8=14-6+4a
4a-4a+8=8+4a-4a
8=8
Is 8=8? Yes. Therefore this is a true statement with no value for x. Infinite solutions or all real numbers.
Answer:
The domain of f–1(x) is all real numbers and the range is all real numbers greater than 0.

Answer:
(5,-3)
Step-by-step explanation:
On the x-axis, go 5 points to the right and on the y-axis go 3 points down the the negative 3 and the point N crosses at (5,-3)
Answer:
B, C
Step-by-step explanation:
7 - x = 18
A.
7 - 2x = 18 - x
126 - 14x = 324 - 18x
We are nowhere near the solution.
B.
-x = 11
x = -11
This works.
C.
7 = x + 18
-11 = x
This works.
D.
25 - x = 36
-25 + x = -36
This does not help.
E.
7 = x + 18
0 = x + 11
We still do not have a solution.
Answer: B, C
Answer:
B- The dependent variable is the amount of money she earns, and the independent variable is the number of hours she works.
Step-by-step explanation:
The amount of money she earns depends on how many hours she works, making that the dependant variable.
